	Choose randomly an element in the structure.

Detailed Description

template<class Self>
struct vcsn::algebra::SemigroupBase< Self >

Base class of all structures that are semigroups.

All derived classes must define type virtual_types<S>::semigroup_kind.

Member Function Documentation

bool contains (  const Element< OtherS, T > &  other  )  const [inherited]

Specialization of contains that always returns false. Indeed, elements structured by a particular type are always incompatible with structural elements of another type.

self_t& self (   )  [inherited]

Accessor to the real type. To be used by implementations in this class and derived structures to obtain a reference to the structural element with its most derived type. Referenced by vcsn::op_contains(), vcsn::op_convert(), vcsn::op_in_mirror(), vcsn::op_letter_delta(), vcsn::op_letter_deltac(), vcsn::op_letter_rdelta(), vcsn::op_rdelta(), vcsn::op_rout(), vcsn::op_spontaneous_delta(), and vcsn::op_spontaneous_rdelta().
